It is well known that in Sluicing constructions wh-dependencies can cross certain projections that are otherwise barriers to movement (Ross (1969), Chomsky (1972)). This fact would follow under the assumption that the relevant barriers are somehow deactivated when phonologically deleted ('island repair'). The problem, however, is that another form of phonological deletion (VP Ellipsis, VPE) seems to be impossible in certain contexts where Sluicing allows for island repair (Chung et al. (1995), Merchant (1999)).
